Ivory v0.1 was released. Ivory is a MapReduce-based retrieval toolkit that supports various retrieval models, including the Markov Random Field model for IR. The project is a joint effort with Jimmy Lin and Tamer Elsayed at the University of Maryland.

I finally updated my CV to reflect what I've been up to for the past two years.

Markov Random Field models for information retrieval -- My thesis subject was Markov random fields for
information retrieval. I investigated both the theoretical side of the issue (e.g. modeling and parameter
estimation), as well as the practical side of things (e.g. how we can use the model to achieve good effectiveness
for various retrieval tasks).

Searching using Markov Random Fields (SMRF) -- A Java-based toolkit being designed to support research into the Markov Random Field model for information retrieval. More details soon!

RECAP -- a tool for exploring, analyzing, and visualizing various kinds of
text reuse within a collection of documents.

Indri -- an efficient, scalable search engine with a
robust query language. Indri, a collaborative effort with Trevor
Strohman and Howard Turtle, synthesizes and enhances the Lemur and
INQUERY search tools. My research focused on the development of the underlying retrieval model and query language.
